Why it works: Lettuce and tomato are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 1,655 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White bread
- Provides the soft, neutral base that holds the filling together.
- Butter
- Adds fat and richness and keeps the bread from soaking up moisture from the filling.
- Crisp lettuce
- Adds a cool, crunchy layer that contrasts with the soft bread and tomato.
- Mayonnaise dressing or rich cream
- Adds fat and moisture, binding the lettuce and tomato and seasoning the sandwich.
- Ripe tomatoes
- Supplies juicy moisture, acidity and sweetness as the main flavour.
